Okay so this doesn't really narrow down the choices too much, so let's think about how living things store energy. Living things generally use energetic molecules (such as ATP) to store and transfer energy, meaning they use CHEMICAL energy.
This means we can eliminate B,C, and D, leaving us with A as the correct answer.
